A nasal douche having a valve, container part and cap part, wherein the container part serves to receive irrigation liquid and carries cap part. The cap part has a nose attachment with an outlet opening for irrigation liquid connected fluidically to interior of container part via discharge channel, wherein nose attachment is intended to be attached to a nostril of the user. The container part or cap part is assigned a mouthpiece for controlling the valve, wherein the valve is closed in a rest position and flow of irrigation liquid out through the nose attachment is thus suppressed, and wherein the valve can be brought to an open position, under the action of respiratory air when the user blows into the mouthpiece, and irrigation liquid thus flows out through the nose attachment, wherein respiratory air or ambient air flows into the container part to allow the outward flow.
